Product-sets
for Shop-Script

You can make dynamic checking, when you delete the product or change the quantity of product on the cart page.

You can't do this without making changes in the design theme, so You need to do the following steps:

Go to Shop - Storefront - Template - cart.js

Add code to the function, which is responsible for changing the quantity of product:
if (typeof $.itemsetsFrontend !== 'undefined') {
$.itemsetsFrontend.quantityChange(that);
}
where "that" - field of product quantity (jQuery object)
